Refactor github repositories.

I think we should change to three github projects.

FirebaseArduino - Will include the FirebaseArduino.{h,cc} and all related examples. Will be exported as an Arduino library.
FirebaseArduinoModem - Will include SerialTransciever.h and modem/ subdirs including tests, and its example. Will be exported as an Arduino Library.
firebase-iot - Will include the core cross-platform logic (Firebase.{h,cc}, transports, etc..) and tests.

I think they should all live under google/ as well instead of googlesamples/ as we are providing libraries to use instead of samples.

This issue will preclude #108 and #92.

What do you think?

I think we should then use submodules to include firebase-iot in the two libraries and add symlinks. The issues with windows and symlinks will just have to be addressed by windows developers I don't think there is any other great way to include part of another library.

what about splitting them logically in the same repo for now?

It will be easier to version and to manage since we'll get atomic commit on the 3 codebases. We can always split later when the projects grows larger.

I was hoping to do just that but I don't think we can release Arduino libraries that way.

I am thinking we could do some shenanigans like do all of our development in firebase-iot (main repo, not an arduino library). Then create the other two repos FirebaseArduino and FirebaseArduinoModem, import firebase-iot as a submodule into them and use symlinks to create the structure that arduino wants for its libraries in those dummy repos.
